Chapter 4 Adjustments and settings for recording (continued) Example 2: When connecting a multiple number of units and using one of them as the reference unit MON OUT (HD-Y) or VIDEO OUT (VBS) TC OUT TC IN GENLOCK IN Reference unit MON OUT (HD-Y) or VIDEO OUT (VBS) TC OUT TC IN GENLOCK IN MON OUT (HD-Y) or VIDEO OUT (VBS) TC OUT To the next camera The system can be configured with multiple units by opening the screen from the SYSTEM SETTING page and setting the GL PHASE item to the connector using menu operations. The phase of the time code can correspond to either the HDY output signals of the MON OUT connector or VBS output signals of the VIDEO OUT connector. However, the same value should commonly be set to the GL PHASE for all cameras. If different values coexist in the system, the shooting timing may not correspond to each other. Reference video signal MON OUT (HD-Y) VIDEO OUT (VBS) Setting of GL PHASE HD SDI COMPOSIT In the unit, there is a video signal delay in the camera, which is required or the process of converting video images taken with the image-shooting element from the progressive signals to the interlace signals. Since time is required for making the 2:3 pull-down from the 24P frame, there is a video signal delay in the camera. When recording from a device that can record images without a delay and the unit is connected in parallel, it is necessary to synchronize the time code. To set this timing, open the screen from the VTR MENU page and set it in the TC VIDEO SYNCRO item. Set by referring to the connection example. Setting of the TC VIDEO SYNCRO item Item TC VIDEO SYNCRO Variable range 0 1 2 3 Remarks For setting to correct the time code according to the delay of video signals. 0: Do not correct. 1: To delay the time code to be input according to the timing of the video images. 2: To forward the time code to be output according to the timing of the video images. 3: To delay the time code to be input and forward the time code to be output, respectively, according to the timing of the video images. Example 3: When the unit and an external device are locked to the external time code generator, which is connected externally, and when simultaneous recording is made by using the TC OUT output signals.

HD SDI: For locking the HD SDI signals to the GENLOCK input. For the down converter output signals, the start position of the video delays by about 90 lines. COMPOSIT: For locking the down converter output signals to the GENLOCK input. For the HD SDI output signals, the start position of the video gains by about 90 lines.
